Disclosed is a processor-implemented method for processing image data of a document using an apparatus. Nanoparticles of a predetermined composition, size, and structure are dispersed in a host medium to create an optical notch filter, thereby attenuating only a narrow range of the visible spectrum. The temporomandibular joint dislocation reduction roller reduces the risk of injury to the patient as well as to the health care professional during the reduction procedure. In an alternative embodiment, the insertion pin is moveably or pivotally mounted to the base member. The method is suitable for mass production in industry, energy consumption is reduced, pollution of the environment is reduced, and discharge of waste is reduced.
